Description
Decides whether or not to generate zero-half cuts for the problem. The value 0 (zero), the default, specifies that the attempt to generate zero-half cuts should continue only if it seems to be helping.
If you find that too much time is spent generating zero-half cuts for your model, consider setting this parameter to -1 (minus one) to turn off zero-half cuts.
If the dual bound of your model does not make sufficient progress, consider setting this parameter to 2 to generate zero-half cuts more aggressively.
